Stainless Steel Pre-Filter

Captures larger particles.

Bio-Guard Filter

Captures particles as small as 0.1 microns.

Ozone Removal Filter

Eliminates harmful ozone gas (O₃) from the home to less than 1 ppb – 70 times less than the EPA’s household standards of 70 ppb.

Bio-Guard 360 Filter

Uses patent-pending electrostatic precipitation (ESP) technology to trap remaining particles as small as 0.1 microns, that’s 66% smaller than anything most HEPA filters can capture.
